特高含水开发期低效井治理方法探讨

A Discussion on Low Efficiency Well Treatment in High Water-cut Stage

摘要: 油田进入持高含水开发期后，低效井井数呈逐年上升的趋势，这些并治理的好坏直接关系到油田开发后期的经济效益。文中主要从油藏工程角度出发，对低效井的成团进行了分类，指出了油田开发后期低效井治理的方向，并探讨了低效井的治理方法。

Abstract: The number of low efficiency wells increases year by year as oilfields go into high water-cut stage. Economic benefits in later production period depend directly on the quality of low efficiency well treatment. This paper gives a genetio classification of low efficiency wells, and presents the direction and methods of low efficiency well treatment in later production period.
